Overview
The LM1085IS-5.0/NOPB is a positive linear voltage regulator from the LM1085 series, manufactured by Texas Instruments. It provides a fixed 5.0V output with a maximum current capability of 3A. The device operates within an input voltage range of 2.6V to 25V and features a maximum operating junction temperature of 125°C. It utilizes a surface-mount D2PAK-3 (TO-263-3) package with dimensions of 10.16mm length, 8.64mm width, and 4.57mm height. The quiescent current is specified at 5mA.
Feature Summary
- Provides a fixed 5.0V regulated output voltage for stable power supply applications.
- Capable of delivering up to 3A of continuous output current.
- Incorporates internal thermal overload and short-circuit protection mechanisms.
Applications
- General-purpose power supplies requiring a stable 5V rail
- Battery-powered systems needing efficient voltage regulation
- Offline switchers used as post-regulators
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via the official datasheet. Ensure the specific suffix matches the required package and temperature grade. Request batch-specific documentation for quality assurance purposes before finalizing procurement decisions.
Selection Notes
Select this component when a fixed 5V output is required with high current capacity. Consider the 25V maximum input voltage limit during design. Evaluate thermal management requirements due to the TO-263 package characteristics. Compare against adjustable variants if flexible output voltages are needed instead of a fixed setting.
Part Context
This part belongs to the LM1085 family of low-dropout regulators designed for general-purpose applications. It shares architectural similarities with other members like the LM1085IS-3.3 but differs in output voltage configuration. The NOPB suffix indicates lead-free construction compliant with environmental standards.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing circuit designs before considering alternative components.
